2.2. Recommendations
ecommendations Before Use
2.2.1. Mechanical
To ensure correct operation of the electronic register, carefully read the following
recommendations before installing the product:
• Make sure the base (or stand) is solid enough to support the weight (20 Kg.)
• Connect the electronic register so that the front door of the case can be
easily opened (more than 90°) to make circuit board maintenance and
replacement operations easier.
• Do not position the case too high so that the operator has a good view of the
display and can easily access the selectors/buttons
• In warm environments, the electronic register should be placed far from
direct sunlight. The external case temperature must never exceed 55 °C to
ensure correct operation of the internal electronics
• Do not use the cover of the rack for cables fixing (maintenance could be
difficult).

2.2.2. Electrical
To ensure correct operation of the electronic register, carefully read the following
recommendations before installing the product.
• Make sure that there is isolation between the DC and AC cables: for the
electronic register wiring use the conduit indicated in the paragraphs below
(see the table below)
• It is advisable to connect the pulser before cable the power supply
• Make sure that all the connectors and that all the screws have been correctly
tightened.
• Make sure the earthing point is as close as possible to the electronic register
(avoid using steel structures and piping as the earthing points).
• Make sure the resistance between the electronic register and earthing point
is not over 2 ohm

3.1. Divestment Of The Product
The WDMM is an electronic product that contains substances potentially
dangerous for the atmosphere and the human health. As indicated from the

4. OPERATIONS MANUAL
4.1. Power On Of The Register
On power on, the WDMM display performs the test phase.

4.2. Operation Modes
4.2.1. General description
Two different operation modes have been foreseen by the WDMM, each of which
is characterized by specific management of operating interface.
4.2.2. Water Draw Mode
The Water Draw Mode (available only on WDMM-01 and WDMM-02) is selected by
the operator when water draw operation has to be performed.
The prover sphere moves in the forward direction and hit the first detector (DS1),
the impulse of DS1 latch the control/inputs relay (normally open), that remain
latched until another impulse is applied, allowing the recording of the pulses on the
electronic counter.
When the sphere hits the second detector (DS2), it send an impulse to the
control/input relays that open the contact and stop recording of the pulses on
electronic counter.
Volume measured from electronic counter is the volume between the two
switches of the prover.
This operation is also carried out in the reverse direction i.e. at the reverse
movement of the sphere, setting the selector accordingly.
4.2.3. Master meter mode
The Master Meter mode is selected by operator when the Meter has to be used as
Master Meter.
Sheet n° 17 of 20
Doc. n° WDMM/02/E
4.3. Water Draw procedure
Working in Water draw mode, the following steps have to be followed
1) Put selector “START” on the Sphere detector to be used as start
2) Put selector “STOP” on the Sphere detector to be used as stop
3) Put selector “MASTER METER/WATER DRAW” on “Water Draw”
4) Push Reset Button
5) Start the sphere for the first run
6) After 1st run, move selector “START” and selector “STOP” accordingly and
push reset button again to measure on backward direction
During water draw operation the light “A” is switched on
IMPORTANT!
Do not select the same sphere detector number for Start and Stop
4.4. Master Meter procedure
Working in Master Meter mode (WDMM-01 and WDMM-02), the following steps
have to be followed
1) Put selector “MASTER METER/WATER DRAW” on “Master Meter”
2) Use the meter as a normal Master Meter
Working with WDMM-03, after starting both Master Meter and PD meter to be
calibrated, just follow the below steps:
3) Switch on WDMM-03 through relevant selector
4) Reset to 0 both displays through pushing “Reset” buttons
5) Start counting pulses through relevant selector
6) Both displays start to count, after passing necessary volume, stop pulse
counting through relevant selector and compare the two volumes
For WDMM-03 only this operation mode is available.
